These insects are found on every continent except Antarctica, and they vary in appearance and behavior depending on the region they inhabit. The most common species of stink bugs that invade homes are the brown marmorated stink bug (Halyomorpha halys) and the green stink bug (Chinavia spp.).
1. Where do stink bugs originate from?

Stink bugs can cause significant damage to crops, leading to economic losses for farmers. They are known to feed on a variety of plants, including fruits, vegetables, and ornamentals. Additionally, their presence in large numbers can disrupt ecosystems and affect the balance of native insect populations.
8. How can I prevent stink bugs from entering my home?
To prevent stink bugs from entering your home, it is essential to seal any openings and repair damaged screens. Installing weatherstripping on doors and windows can also help create a barrier. Additionally, removing vegetation around the perimeter of your home can reduce the likelihood of stink bugs finding their way indoors.
9. Are there natural ways to control stink bugs?
Natural control methods for stink bugs include vacuuming them up and disposing of them in a sealed bag or container. You can also create homemade traps using light sources or soapy water. However, if you have a severe infestation, it is recommended to seek professional pest control services.
